35 would be positive while 40 would be negative
Given: 3.2*10^2-8.7*10^6
Exponents: 3.2*100-8.7*1000000
Multiply: 320-8700000
Subtract: -8699680
Scientific notation: -8.69968*10^6
Answer: -8.69968*10^6 or -8.69968*10e6
Answer: There is a 2.9% chance that a person has head lice given that the test is positive. (I know that sounds very low, but watch the math)
Imagine there are 10,000 students in the school. If 1% have lice, that makes 100 students that have it and 9,900 that don't.
Assume the test was given to all students. Out of the 100 that have lice, only 75 would get a positive test because it is only 75% accurate.
Now, out of the 9,900 student who don't have lice, 25% of them would get a positive test, because the test is only 75% accurate. That is 2,475 false positive tests!!!
So we had a total of 2,550 positive tests, but only 75 of those students actually have lice. 75 out of 2550 is 2.9%.
The Domain and Range of tan(x) are mathematically given as
Domain
Range: all Real numbers
<h3>What is The Domain and Range of
tan(x)?</h3>
All real numbers are in the domain of the function "y=tan (x)," with the exception of the value "" for all integers n, which is the case when cos(x) = 0.
It follows that "" is not in the domain of "tan (x)" among the possible values.
In conclusion,
Domain
Range: all Real numbers
